DIGITAL RACK INTERFACE POD SYSTEM AND METHOD INCORPORATING LOSSLESS, PARTIAL VIDEO REFRESH FEATURE

摘要

An apparatus and method for lossless compression of digital video data being transmitted from a first electronic device to a second electronic device. Pixel locations of grids of first and second video frames are analyzed to determine which pixel locations of the second video frame have pixel values that have not changed from those in corresponding ones of the first video frame. Commands are sent identifying individual pixel locations in the second video frame that have pixel values that have not changed from those present in corresponding ones of the first video frame. The commands are used when updating the first video frame to match the second video frame. Additional commands identify those pixel locations in the second video frame that have pixel values that differ from corresponding ones of the pixel locations in the first video frame.
